Discussion

Species 2 (1 in the flora).

Chorizanthe brevicornu of western North America, and its counterpart in western South America, C. commissuralis J. Rémy, are the most widely distributed members of the genus on their respective continents. The flowering stems and branches easily break apart, often with involucres still firmly attached. Even in this disarticulated condition, young achenes will continue to live and mature. No doubt this is a significant factor in their successful distribution.
